As any car that clocks miles and is used regularly, be it singly or loaded with passengers, it is the Air Conditioning (HVAC) system that maintains the interiors clean provided the interiors are cleaned regularly and also A/C being used regularly (read windows rolled up) giving the occupants as much as possible clean air to breathe. Also the Air filter keeps the engine breathing cleaning so we get better performance, FE and reliability.

It is a good practice to clean these at regular intervals so they have a longer service life.

The load generally falls on the cabin air filter that is placed in between to not let the dirt/debris get through via the A/C ducts. Now the secondary unit that takes the load is the blower and the motor itself. If that itself is dusty and debris laden, it will simply push all that through to the filter then into the cabin.

With 66,000 kms on the odometer and IIRC I had opened the blower at 4K kms when the car was new to check, it has been approximately 62,000 kms since I have opened the blower unit to clean. I drive through heavily dusty areas, certain times the visibility is low due to the dust that is in air thanks to "no-roads" that I travel on. This makes the cabin air filter dirty very quickly hence needing the cleaning at regular intervals.

I was noticing that the sound of the blower was slightly on the higher side when at position 1 and 2, hence made me think if the blower was dirty requiring cleaning making the need for this DIY.

This time I thought why not put up a thread so it could help fellow others too for cleaning the blower and filters as well rather than spending bucks and donating it to the ASC for the same job.

Tools Required:

1 x Rachet handle
1 x Extension rod
1 x 8 mm flank socket
1 x Cloth for wiping / cleaning
1 x Pressurized air blower

1) For the engine air filter, the box contains 4 screws on the 4 corners that need to be removed to free out the top cover to get access to the filter. Be delicate in handling as the top cover is connected to the MAF sensor.

2) For the cabin air filter, one needs to remove the glove box to get clear access to the A/C unit and filter cover.

Hai Anuraag,

i have tried this morming to remove the Blower unit from my ritz but its not able to succeed as the blower unit is fixed very inner side of the AC unit.

The screws are different.i don't think this one can be removed as DIY.

Any one tried of removing the Blower in any ritz can help me out.

Last 2 weeks the blower unit sound with humming noise as the blower is stuck with some dust particles i think..........

Hi Anurag,

Can you elaborate on how you cleaned the blower fins?

I used a cloth wrapped to flat head screw driver and passed along the fins, I could clean most of the fine dust, but was not 100% clean.

Cheers,
Darshan
